Insight
Insight
It was discovered that there was a authentication bypass vulnerability in libxslt, a widely-used library for transforming files from XML to other arbitrary format. The xsltCheckRead and xsltCheckWrite routines permitted access upon receiving an-1 error code and (as xsltCheckRead returned -1 for a specially-crafted URL that is not actually invalid) the attacker was subsequently authenticated.
Affected Software
